I'm so happy you posted this question. Kiki has only been home with me less than a week. She's a 2-yr-old rescue. In the past I've owned mini doxies. She was spayed last Thursday and on Sunday I had to leave for a few hours. Came home, took her out of the crate and............. omg,,,,,, she was a speed demon.
I tried to contain her because of the recent spay and she wriggled right out of my hands and ran around like crazy
So happy to hear this is normal ~ well, as normal is, I guess ~ lol
